I once owned a Dicomed field Pro, a predecessor to the Betterlight and also made under Mike Collette's supervision. The quality, with the right subject, was fantastic, but something of a hassle to lug around in the field. Insane really, because only static subjects are suitable. However they are the only choice if you presently want to mirror the effect of LF film, as we have no single shot sensor for large format I am aware of. Fun to play with but impractical in daily use for most of us.
